The fact you have gone 12U and 300GB raw is just the change in technology. Compression, deduplication and SSD/NVME all contribute to the reduction in size. As with any vendor, the grass is usually greener in the other field as new kit does not have as many failures. 7 racks for a PB is very low density/old kit so high failure rates and lots of support calls should be expected.
